Adaptability is a tough question for me. I used to attend a studio where all classes were adapted to the students in attendance. So, if the majority of people present were beginner students, every class became a beginner class. That was great for the beginners, but it became very frustrating for advanced students, who may have drive fifteen minutes to an hour for an advanced class, only to find at the last minute that it was actually a beginner class they were attending. Needless to say, given the proportion of beginner to advanced students, after a while, the advanced students stopped attending classes altogether. :?
